GB/T 35954-2018 Determination of 10 whitening and freckle-removing componentsin cosmetics—High performance liquid chromatography
Basic Information
Scope
This standard specifies the reagents and materials, instruments and equipment, analysis steps, result calculation, recovery rate and precision, and allowable deviations for the high-performance liquid chromatography determination method of 10 whitening and spot-removing agents (magnesium ascorbyl phosphate, ascorbic acid glucoside, β-arbutin, kojic acid, niacinamide, 3O-ethyl ascorbic acid, potassium methoxysalicylate, raspberry ketone glucoside, dipotassium glycyrrhizinate, and 4-butylresorcinol) in cosmetics. This standard is applicable to the determination of 10 whitening and spot-removing agents in water-based, emulsion, ointment, gel, wax-based, and powder-based cosmetics. The detection limit and quantification limit of the standard method are shown in Table A.1 of Appendix A.
